A new design approach for the established flow region of vertical, dilute-phase pneumatic conveyors KU Leuven
Evaluating conventional and deep learning segmentation for fast X-ray CT porosity measurements of polymer laser sintered AM parts KU Leuven
Laser sintering is evolving towards a genuine manufacturing technique for volume production and mass customized products. However, variability in part quality has to be reduced further to enable its use for high demanding and critical end-use applications. High volume and mass customized manufacturing impose the need for a fast and flexible measurement instrument, to automatically assess the overall part quality, which is currently not available ...
Incorporation of bioleached sulfidic mine tailings in one-part alkali-activated blast furnace slag mortar KU Leuven
Sulfidic mine tailings are potential waste materials from mining and mineral processing, and they can contain a high content of sulfur and metal(loid)s, even after bioleaching. Due to the large amount of tailings waste from historical mining, it is crucial to find alternative methods for utilizing such waste rather than permanent storage in tailings impoundments. One-part alkali-activated slag mortars are promising co-binder systems for the ...
Recycling of unseparated construction and demolition waste (UCDW) through geopolymer technology KU Leuven
Geopolymer technology has been recognized as an ideal option for recycling construction and demolition waste (CDW) streams as new value-added products. However, most research efforts have been devoted to the geopolymer derived from the individual fraction separated from CDW. Given the technological complexity presented in separating CDW fractions on a commercial scale, using unseparated CDW (UCDW) in geopolymer application can achieve higher ...
All-Optical and One-Color Rewritable Chemical Patterning on Pristine Graphene under Water. KU Leuven
We report a facile all-optical method for spatially resolved and reversible chemical modification of a graphene monolayer. A tightly focused laser on graphene under water introduces an sp3-type chemical defect by photo-oxidation. The sp3-type defects can be reversibly restored to sp2 carbon centers by the same laser with higher intensity. The photoreduction occurs due to laser-induced local heating on the graphene. These optical methods combined ...
